SODAeFOUNTAIiN SYRUP-PUMP.

To all whowi it may concern: l

Be it known that l, FnnnRrcK HENRY HncKER, a' citizen. of the UnitedStates, and a resident of Los Angeles, Los Angeles county, California,have invented certain new and useful Improvements in Soda-FountainSyrup-Pumps, of which the following is a specification. f This invention4relates to pumping apparatus and has particular reference tosyrup-pumps for soda water fountains. The object of the invention is toovercome prominent defects in4 prevailing types of syrup pumps in,thesimplest possible manner.

A part of the equipment of a modern `soda-water fountain is a series ofsyrup bottles or receptacles containing juices or syrups of differentflavors designed to meet varying tastes of customers. Instead of pouringthe syrup from the mouth of thebot-.tle or receptacle it has been foundmore convenient to permit the bottles or tube terminatingin a spout anda valve arrangement whereby a depression or longitudinal movement of thetube itself causes the liquid to flow therethrough and out of itsoutlet. To this end the tube is equipped with a piston and thereceptacle isy provided with a piston-chamber and a valve mechanismconstructed to either lill the chamber by suction or by gravity flow..lhe operation of filling the chamber by suction creates a noise orsound which is objectionable to both user and customer and the operationof filling the chamber by gravity flow is wasteful of time as the pistonmust usually be raised to a point in the chamber where the inlet theretois uncovered at the end ol the upward stroke o the piston. '.l`oovercome this delay and at the same tinnthe rushing noise produced by aliquid entering la chamber by force of suction, I have provided n.piston possible to force liquid from the chai'nber without wait ing forthe piston to:return to the end ol its upward movement and then waitingfor the piston-chamber to lillu up by gravity.

With tlleabovcobjects in view my invention consists in thc novel syruppump and in its combination with a .syrup receptacle hereiintl'terdescribed in detail, illustrated in the drawing and dclincd in theclaims.

,in the bottom of the vessel 2.

diameter' than the -chamber i4 in the body of the vessel Patentes. July2S, 19071' Figs. 4 and 5 represent vertical or transverse sectionsthrough two forms of pistons which are modifications of the piston shownin Fig. l. Fig. 6 illustrates the lower portion of a modified form ofsyrup-vessel, or piston-chamber, adapted for all of the vseveral formsof my invention.

Referring in detail to the several views, 2 represents asyrup-receptacle, bottle or vessel and 3 represents another fornithereof. The vessels 2 and 3 are equipped with piston-chambers,measuring cups, or trap-chambers 4 and 5, and except for the latter, theforms of the vessels are immaterial.

In Fig. 3 is shown a piston-chamber 'which makes my inventionindependent of any l'orm oi vessel, including the bottornportions 4 and5. In either of .the chambers 4, 5 andl is arranged a piston consistingof a perforated disk 7, secured to the piston-rod or outlettube 8 nearits lower end, and a similar perforated disk 9 which has a limitedmovement along the rod 8. While the two disks 7 and 9 are perforated,the perforations of the upper disk 7 do not register with the lower diskperforations, so that when the two disks lie closely against each otherthey form, substantially, animperforate piston, the imperforate portionor portions of one disk covering the perforations of the other disk,shown in Figs. l, 3, 4 and 5. Figs. l and 3 illustrate one form of upperdisk, while Figs. ll and 5 illustrate two other forms thereof.

In Figs. l, 3 and 4 the upper disk 7 is shown provided with perforations'.ll which correspond to the perforations l0, but in Figs. l and 3 theperforations l0 and Il] are closed against communications with eachother by the adjacent laces of the disks 7 and 9 when the latter lie asclosely against'each other as the annular flanges or ridges l2 in Fig.ll, or the peripheral flange. 13 in Fig. 5, permit. The objects of said[langes or ridges is to prevent the disks from sticking together whentho piston-rod 8 is raised. (.)rdinarily the adjacrnt iar'zes oi th(`disks will not stick together suflicicntly to prevent their separation,out for the purpose of rapid operation it may be desirable to reduce thesurface contacts by means of the ridges l2 and f3. Said ridges close thedisks to each other so that -liquidrzannot normally passy from theperforations ll into the pei-fora tions ld. g. Y

Referring, first, spocllically Ito, .the construction shown in Figs. land 2, the piston-chamber 1l is formed The chamber 4 isof less openingsVl7 and lS from the chamber' 14 into the chamy bcr 4 when the piston isat its highest point as in Fig. l, .lu Fig. 3 the chamber (i correspondsto the chamber with the exception that the chamber (3 isa separatevesmally raised position shown in Fig.A l.

sel which may be placed in any ordinary syrup-jar or -receptacle thatwill receive it. Openings 19,. corresponding to openings 17 and 18, areprovided in the uppery part of the vessel or chamber G. ,lnl the con- 5struction shown in Fig. 6 no openings l7, oi 19 are provided for thechamber 5.

The piston-rod 8 provides a tubular passage through which the liquid isforced from either chambers 4, 5er (i and at that portion of said rod ortube which is at the l 0 top ofthe jar or vessel 2 is a flange 2O whichbears against 20 counter-top 26 having a perforation 27 for the jar 2.28

is a knob or handle arranged on the upper end of the piston-rod and tube8 for convenience in operating the piston. Asshown, thespout, or outlet,29 communicates with the passage in the rod 8 through the handleportion28, whereby a continuous passage 30 is formed between the chamber 4 andthe mouth of the spout 29, or the chambers 5 or (l and said spout.

In Fig. 3 where an independent chamber 6 is provided, the lower end ofthe spring 21 bears against the 30 top of a sleeve 3l which rests on aboss 32 on top of the chamber (i.

A disk or flange 33 secured to the upper end of the tube 8 bears againstthe top of the spring. In the latter construction the sleeve v31performs the function of the bottom 22 in Fig. 1 and the flange 33serves in the same capacity as the flange 20 in said Fig. l..

The lower and movable disk 9 is held against dropping off the lower endof tube or rod 8 by means oi a nut 34 threaded on the lower end ofthemember 8. A recess 35 is formed in cach of the piston-chamber .bottomsadapted to receive said nut so as to permit the piston to move close tothe piston-chamber.

The operation of my invention is as follows; The lower disk 9 normallyrests on the nut 34 leaving a space between the upper disk 7 and saidlower disk i).

The spring 21, or whatever equivalent means is employed, normally holdsthe pist-on in the elevated position in which it is shown in Figs. l, 3and 6. In this position liquid poured into the vessel 2 will be free toflow through the pcrforations 1l into the space between disks 7 and 9and thence through the perforations l() into the piston-chamber 4, 5 or(i. When the hollow piston-rod 8 is pushed down the disk 9 is forcedagainst the disk 7 by the resistance of the liquid or syrup in thepiston-chamber. Forcing the two disks together closes the space betweenthem, which space is the only means of communicationbetween thenon-registering perforations l0 and ll. A ',lhe piston then becomessubstantiallyan imporforate piston which closes the pistoncbambor 4, 5or-fil against the chamber 14. 'lhc liquid l i nes-m lire piston-chamber1s therefore forced up through thi-:.-fpassagc 3() and out of thc spout2S), Tho chief adv:| irl-1go of my invention is made apparent in thcreturn stroke of thc piston. Instead of it boing necessary to rribve thepiston upwardly a definite distance on its rcturn-stroke, for th(lpurpos.:I of uncovcriugan inlet-port,

is true of the openings in the disks. of any suitable form, the onlylimitation being that the or for'tlie purpose of refilling thepiston-chamber by suction, the very moment the return, or upward, Inove-'ment of disk 7 begins the disk 9 drops away fronrclosing contact withsaid disk 7 and permits the liquid to flow into the piston-chamber whilethe pistori-*comprising disks 7 and 9-is moving upward. The rcillings ofthe piston-chamber are therefore comparatively noiseless as well ascontinuous during vthe upward strokes of the piston and the piston may,at the same time, be stopped at any point short of its highest positionwithout affectingr the operation of forcing the liquid through the pasesage 30. The latter flieature is emphasized in Fig. 6 where no openingsi7, 18 or l j, above which the piston may rise', are provided.These(imparativcly quietl and rapid refilling of the pistozfehamber isvery important at a busy fountain and where a plurality of glasses areto be supplied with the saine syrup for the purpose of filling a singleorder.

'lhe two disks of the piston need not both fit the piston-chamber. Oneof the disks may be o1' any desired form so long as it is arrangedtoclose the openings in the other disk when both disks come together.

The latter may be openings through one disk do not register with theopenings in the other disk, or that both disks together have a formwhich is adapted -to close the entrance to the space beneath the piston.Aside from thisit is immaterial how much or how little of their combinedarea cach piston-disk or plate covers.

The preferred construction lshown in the drawings has, among others, theadvantage that the liquid bevalves are easily dis-arranged and madeinoperative while th e closure between the two disks is, if anything,improved by wear of their adjacent faces produced by their contacts.

What I claim as new and desire to secure by Letters Patent is-H 1. 'l'hocombination 'with a syrup receptacle, of :1 mensurlng chamber in thebottom of said receptacle, a combination piston-rod 'nnd outlet-tube,and a piston in said chamber, comppsod of a plurality of` disks eachmounted on said lube and separable one from another to constitute anormally open valve adapted to admit liquid -to the chamber when theparts are separated.
